noon rnAcKnNn HANGER.

Be it known that we, JACOB D. WELLIVER and WILLARD G. HARRINGTON,citizens of the United States, residing at Scranton, in the county ofLackawanna and State of Pennsylvania, have invented certain new and:useful Improvements in Door Tracks and Hangers, ofwhich the followingis a specifioatio n.

1 Our invention comprisesimprovements 1n tracks and hangers especiallyadapted for freightcar doors, but suitable, also, for other structures.

The details and advantages of-- our improvements will be clear from thefollowing 1 specification, taken in connection with the accompanyingdrawing in which,

Figure l is a front view of the track and hanger, showing also the upperend of the door; Fig. 2 is a rear View ofthe track; Fig.

' 3 is a vertical section through the track and hanger on a larger scalethan the other figures of the drawing; .Fig. 4 is a front view of thehanger; Fig. 5 is a plan view of. the ball retainer, and Fig. 6 is asection through vthe track and hanger on the-line 6-6 of Fig. 3.

Referring to the drawing A-indicates the track, B indicates the doorhanger, C indicates a ball retainer or spacer which fits loosely betweenthe opposing parts of the track and hanger and 1, and 2 indicate metalballs arranged in suitable openings in-the end portions of the ballretainer or spacer.

The-hanger B consists of a metal bar, equal in length to theWidth'of-the door D and having a fiat portion b, secured to the upperend of the door, at the rear side of the latter, and a part b projectingoutwardly.

above the .door and of substantially semicylindrical shape in crosssection, forming a race-way on the hanger.- The track A' comprises ametal bar, approximately twice as ong as [the hanger, but of course thelength of the track will depend. upon the width of the doorway and thelapof the door over the sides of the doorway. The track is adapted to besecured in horizontal position above the doorway by suitable means suchas the bolts 3 passing through a seriesof perforations 4 near the upperedge of the track. The track has two reverse bends 5 and 6, eX

tendinglo ngitudinally thereof, which give, the track an ogee shape incross section, as-

shown in Fig. 3. Thus when the track is in position upon a car bodyor.other structure,

E, the central partc of the bar, between theoutward .bend 5 and inwardbend 6, inclines away from the structure to which the track is attached,and forms a shield to protect the parts beneath it from the weather andfrom cinders, etc. The inwardly turned portion a of the track, below thebend 6, is semicylindrical in cross section, and forms a raceway for theballs 1 and 2 which are arranged between the track and hanger, withinthe race-ways, as shown. Where the race-way portion a, of. the trackjoins the body portion, the upper edge 7 of the race-way is faced offhorizontally in the same plane as the edge 8, and similarly the edge 9of the race-way b is faced off arallel with the edge 10, so'that theedges of the walls of the two race-ways are posed, but separated by theballs 1 and 2, when the hanger is in position. Within the recesses e andbetween the opposing edges of the race-way walls, is ar ranged the ballretainer or spacerC. This ball retainer as shown in'Fig. consists of afiat strip of metal, approximately one half as long as the door hanger,and having near its ends circular openings 11 and 12 of slightly greaterdiameter than the diameter of the balls 1 and 2, which fit looselywithin the.open,ings. y i

Stops 13 and 14 (Fig. 6) are provided at the ends of the race-way b" ofthe hanger, these stops being arranged to engage the uper halves of theballs, to prevent the latter rom working out under the hanger, and theend portions 15 and 16 of the race-way a of the track are slightlyelevated, as shown in upon the raised art of thetrack, as shown indotted lines in ig'. -1 and in full lines in Fig.

6 When the door i'smoved to the left in Fig. 1 the hanger will rollalongon the balls and in the extreme left hand position of the door the balllwill be about at the center'of the hanger and the ball 2at'the righthand end of the hanger while the left hand end of the hanger will be suported by the adjacent raised portion 15 of t e track.

The ball retainer or spacer keeps theballs' a certain distance apart,equal to a little less than one half the width of the door. the doormoved away from one end of the track it rides freely on the halls untilit approaches the opposite end of the track," when one end of the hangerwill ride onto the raised portion of the track, and this engagement ofthe track and hanger will frictionally retard the movement of the doorand also hold the door frictionally in position, The track may beclosedat its ends if desired, to prevent the entrance of snow, rain, cinders,etc.

hat we claim is I I 7 1. A track comprising a metal bar having a partnear one edgeadapted for attachment to a car or other structure, andhaving its central portion inclined outwardly to form a shield auditslower portion turned inwardly and curved to forma raceway, said racewayhaving parallel upper edges, in combination with a hanger comprising abar having a flat portion ada )ted .for attachment to the upper end 0 adoor, and having' its u per portion turned outwardlyand curved to iorm araceway, said latter raceway having paraltrack raceway and l'iavingstops at its ends, a ball retainer comprising a flat plate arrangedbetween the .raceways of the track and hanger, and supported upon theedges of the track raceway, said plate having openings therein spacedapart a distance equal to approximately one half the width of a door,

When 1 lel lower edges opposed. to the edges of the having parall andballs within said openings between said stops.

2. A track com ')rising a metal bar having a part near one edge adaptedfor attachment to a car or other structure, and having its centralportion inclined outwardly to form a shield and its lower portion turnedinwardly and curved to form a raceway, said raceway el upper edges theends of whichv extend slightly above their intermediate portions, incombination with a hanger comprising a bar having a fiat portion adaptedfor attachment to the upper end ofa door, and having its upper 'iortionturned outwardly and curved to lorm a raceway, said raceway havingparallel lower edges opposed to the edges of the track raceway, andhaving sto s at its ends, a ball retainer comprising a at plate, shorterthan the hanger, arranged between the raceways ofthe track and hanger,and supported upon the edges of the track raceway, said p ate havingopenings therein" spaced apart a distance equal to approximately onehalf the width of the door, and balls within said openings between saidstops.

In testimony whereof we aflix our signatures, in presence of twowitnesses.
